The Pancreas and Diabetes

In the Name of Allah, The Most Gracious, Most Merciful
What are the functions of the Pancreas in human body?
1. The role of the substances produced by the Pancreas:

In fact, this common and widespread disease, diabetes, results from the fact that the Creator, Allah, All Mighty, has endued man with a special magnificent gland called “the pancreas”. As soon as food gets into the stomach and reacts with the digestive gastric juice, it turns into an acidic substance. This acidic substance instigates special nerves, located in the walls of the intestines, which instigate the brain to give orders to the pancreas to produce substances and juices that regulate the degree of food acidity. In other words, the first and foremost job of the pancreas is that it produces, under orders by the brain, substances and juices that make food alkaline. This is the first job of the pancreas.
2. Changing the sugar stored in the liver and muscles to make it burnable:

The second job of the pancreas is to change the sugar stored in the liver and muscles and make it burnable. This is because sugar existing in the human body is of two kinds: one for storing and another for consuming; and a special hormone from the pancreas must interfere in order to make stored sugar burnable.
3. Producing insulin:

Another very important job of the pancreas is that it produces insulin that makes sugar consumable and burnable. If the pancreas fails to produce insulin, sugar begins to show in urine, and burning of food weakens in the body. Yes, indeed! It is but a tiny gland, the pancreas, about which most people are careless, yet it does most important jobs. Such is the Make of the All Wise and Omniscient Creator, Allah, Glory to Him, Who says,
“And also in your own selves, will you not then see?!” [Al-Baqara; 21]
Human body is a sign:
In brief, in our human body lurk innumerable magnificent Signs that bespeak Allah’s Infinite Greatness. If we spent all of our lifetime enumerating and contemplating such Divine Signs, we would never be able to do so. Glory to Allah, Lord of all worlds, Who created man in the very best stature, Who shaped man in the very best shape, and Who made man in the very best make!
Praise be to Allah, the Lord of Creations
